GAS-STOVE Specification of Letters Patent.

Patented Sept. 3, 1907.

Application filed June 2,1906. Serial No. 319,830.

To all whom 'it may concern:

Be it known that I, WILLIAM H. OALKINS, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Gas-Stoves, of which the following is a specification.

My invention relates to gas stoves and has for its object the provision of a stove of this character, con structed in such manner as to provide considerable radiating surface in combination with fines for conducting the products of combustion through the fines in such manner as to secure a high efficiency.

A further object of the invention is the provision of a gas stove constructed in such manner as to prevent the fumes from the gas escaping into the room in which the stove may be situated.

Further objects and advantages of the invention will be set forth in the detailed description which now fol lows:

In the accompanying drawing: Figure 1 is a perspectiveview of a gas stove constructed in accordance with the invention, with certain of the parts broken away to more clearly illustrate the construction of said stove, and, Fig. 2 is a transverse verticalsection of the stove.

Referring to the drawing, the numeral 5 designates a base flange which is mounted upon legs 6. Mounted in turn upon the base flange is a rectangular casing 7 which is divided by a vertical wall 8 and a horizontal wall 9 into a combustion chamber 10 and an air chamber 11. The top of the rectangular casing 7 is perforated for the passage of fiues 12. The upper ends of these fiues terminate in and lie flush with a plate 13 as also does a hot air drum 14. The flue 16 which leads to the chimney, enters the rear of the hot air drum as is clearly illustrated in both of the figures of the drawing.

As is best illustrated in Fig. 2, a chamber 17 is formed between the plate 13 and a cap plate 18, said chamber being in communication with the combustion chamber 10 through the flues 12. A burner 19 to which gas is supplied through pipes 20 is located at the bottom of the combustion chamber. The front wall of the air chamber 11 is perforated and is preferably formed of ornamental scroll work. The bottom portion of the rectangular casing 7 which forms the air chamber, is open to the atmosphere.

A door 23 may be hinged as at 24 in such manner as to close the front of the combustion chamber when desired.

The operation of this stove is as follows: Gas being admitted to the burner 19 through the pipes 20, and being ignited at said burner, the products of combustion pass upwardly through the fines 12 into the chamber 17 and then downwardly through the hot 'air drum to the flue 16. Since the walls 8 and 9 form the top and rear wall of the combustion chamber, it follows that said walls will be highly heated. Air passing upwardly through the vertical portion of the air chamber 11 and across the top of the wall 9, is thoroughly heated. This air passes through the scroll work forming the front of the air chamber 11 and into the room. The large drum presents considerable radiating surface and throws off heat, which assists in heating the room.

From the foregoing description, it will be seen that a simple and eflicient gas stove providing large radiating surface and means for bringing air from the atmosphere into contact with the highly heated parts thereof, is herein provided, but while the elements shown and described are well adapted to serve the purposes for which they are intended, it is to be understood that the invention is not limited to the precise construction set forth, but includes within its purview such changes as may be made within the scope of the appended claims.

What I claim, is:

1. A gas stove comprising a combustion chamber open at the front side, a gas burner located in said combustion chamber, an air chamber located partly in the rear of the combustion chamber and partly above said combustion chamber, said air chamber being open at the bottom to the atmosphere and likewise being open to the atmosphere at the front side of the stove, means for conducting the products of combustion from said combustion chamber, said means comprising a drum located above the air chamber which is closed at its lower end and open at its upper end, a compartment into which the upper end of said drum opens. a plurality of flues leading from the combustion chamber to said compartment and a'fiue 1eading from the lower portion of said drum.

2. In a stove, a casing comprising a combustion chamber, a gas burner located in said combustion chamber, a second casing larger than the combustion chamber and forming an air chamber between the rear wall of said combustion chamber and the rear wall of said casing and between the upper wall of the combustion chamber and the upper wall of said casing, said air chamber extending across the top of the combustion chamber, the front wall of said second casing being open at the front portion above the combustion chamber, and the air chamber formed between the rear wall of the combustion chamber and the rear wall of the second casing being open to the atmosphere at the bottom thereof, a large centrally located drum which is closed at the bottom and open at the top, :1 ilue leading from said drum, a chamber located above said drum into which said drum opens, and a plurality of flues which extend from the last named chamber through the upper wall of the second casing and through the air chamber which lies above the combustion chamber and establish communication between said combustion chamber and the chamber which is located above the drum, the products of combustion passing through said flues upwardly to said chamber and then downwardly through the drum to the fine that leads from the drum.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM H. CALKINS.
